You can use a spectroscope to identify the components of solutions by separating the various colours of the components. This can also to convert and breakdown the compounds into individual elements.
A solution has two components: a solvent and a solute. If the solvent is a gas then the solute must be a gas. If the solvent is liquid or solid then the solute can be gas, liquid or solid.A solution is a homogeneous mixture of the solvent and solute such that the bits of the solute cannot be seen by the naked eye. It is a stable mixture whose components cannot be separated by mechanical means.
A solution.
A heterogeneous solution combines 2 or more solutions that are not chemically combined. A homogeneous solution is when the components are uniformly distributed.
A solution contains a solvent and one or more solutes. It is classified as a mixture because when a substance is dissolved in another substance, the two substances are still the same substances, not having undergone any significant chemical change, they are just mixed together.
Boiling off the water from a salt solution will separate the solid salt and water (which can be collected by a condenser).
